My Internet Explorer 7 is screwing up. Every time I download anything from the net, my download cuts out prematurely and tells me to re-download. This is getting really annoying, especially since I want to download Mozilla firefox to try and fix my problem, but I can't! As well, every time I open IE, 2 windows open up instead of 1. One of these windows being my normal homepage, and the other being a blank page from an older Version of IE. Can anybody tell me why this is happening and suggest how to fix it?
